EL ECTRIC ANNUNCIATOR SYSTEM.

SPECIFICATION forming part of Letters Patent No. 453,416, dated June 2,1891.

I Application filed September 25, 1890. $erial No. 366,063. (No model.)

T0 aZZ whom it may concern.-

- Be it known that I, LoUIs M. PINOLET, a citizen of the United States,and a resident of Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful Improvements in Electric AnnunciatorSystems, (Case 2,) of which the following is a specification.

My invention relates to electric annunciators provided with means forindicating the numbers of rooms in ahotel, dwelling-house, arcade, orsimilar establishment.

The object of the invention is to provide simplicity of construction,economy of space occupied, and efficiency of operation.

The number of any room is indicated on the annunciator by pressing, forinstance, an electric push-button in said room. The number remains untila person in another room presses abutton, when a correspondingly-newnumber appears in the place of the prior number without any intermediatesetting or adjustment of the instrument by internal or external means,except that which takes place after the pressing of the button.

The invention in all its details and operation is described by referenceto the accompanying drawings.

The device represented is one which would serve to indicate sixteenindependent rooms or sections of a building; but those versed in the artcould construct an instrument from the instructions herein contained forindicating the numbers of rooms in the largest hotels.

Figure 1 is a plan of a complete annunciator, including a signal-bell. Aportion of the instrument is shown dotted underneath the rotary disks,which are provided with digits. Fig. 1 shows a diagram of part ofFig. 1. Fig. 2 is the same as Fig. 1, except that the disks are removed,making clearly visible parts not shown in Fig. 1. Fig. 3 is an elevationof the instrument as it appears when looked at from the left-hand sideof Fig. 1, it being a side elevation. -Fig. 4 is an end elevation aslooked atfrom the lower part of Fig. 1, the base-board being sectionedat X, magnets 7 and 8 being omitted. Fig. 5 is a diagram of the completeelectric circuits which would be employed for equipping a hotel ofsixteen rooms.

All the magnets are shown and also the generator. In all the figures theinstrument and circuits are shown in a normal condition. The room lastindicated is number 14, the arrow Y pointing to the number.

I11 practice the instrument will be covered bya box with a hole, throughwhich any number in the same position as 14, opposite the arrow Y, wouldbecome visible.

The device, in so far as concerns the signal and electro-magneticmechanism for rotating the disks, consists of the combination of anelectro-magnet a, provided with the usual vibrating armature b, to whichis attached a clapper c in the ordinary manner, a ratchetwheel (Z,provided with a hub e, cylindrical in form and having a piece ofinsulation f embedded in one side thereof, against which presses anelectric contact-spring g in the normal condition of the device, adouble pawl having two parts h and h engaging with the ratchet-wheelupon opposite sides and attached to said armatureupon the projection b,the ratchets h and 71 being engaged with the teeth of said ratchet-wheelin such a manner that the vibratory motion of the armature will rotatethe disks in the direction of the arrow Z, and a pillar or standard 6,on which the said wheel is loosely mounted, so that it may rotate.

Upon the wheel d is mounted a tube 3, which carries two concentric disksm and m, which are held frictionally by means of fibrous disks n orpressing upon opposite sides of the disks m and m. There is sufficientfriction among the several disks to communicate motion to the disks mand m, and at the same time little enough friction to permit ones handor similar resisting force to stop either one orboth of the disks m andm without stopping the tube j, .which fits tightly upon the hub t of thewheel (1.

Upon each disk or and m and upon the under side thereof are locatedprojections o and 0 on the disk on and p and p on the disk m, the formertwo being at different distances from the periphery of the disk m, andthe latter two being at different distances from the periphery of thedisk m. Such a disposition is necessary, as hereinafter de- Y scribed,to allow a wire upon a given armae ture to stop the disk at apredetermined point by the act-ion of one projection or at anotherpredetermined point by the action of the other projection.

Arranged around the standard 1' are solenoids or small magnets l 2 S t 56 7 8. Magnets 1 and 2 have acommon armature q,from which project upwarda wire 7', the magnets 3 and 4 have a common armature g, from whichprojects upward the wire 0'', the mag nets 5 and 6 have a commonarmature (1", from which projects upward a wire r", and the magnets 7and 8 have a common armature q', from which projects upward a wire r.The common armatures are pivoted at the lower ends upon the supports .9.The

lower ends of the wires 1' 'r r" 0"", being secured to these supports,serve as retractile springs for normally retainingthe armatures q q qq', balanced midway between the poles t of the magnets. The wires 'rr'0'' 1"" have normally such positions relatively to the projections 0 op 1) that the disks m on may rotate freely without being stopped by thesaid wires. lVhen, however, any one of the armatures is attracted to oneof the magnets it comes in the path of one of the said projections andcauses one of the disks to stop. Thus if the wire 0 is moved by themagnet 2 the projection 0 will strike it when the wheel is rotatedsufficiently. If the wire r is moved by and toward the magnet 1,the diskm will be stopped by the projection p coming in contact with said wire.In a similar manner the wires 0" 9" 7" may cause one or the other of thedisks m m to stop at predetermined positions.

In Fig. 1 the number 14, opposite the arrow Y, was formed by the wire 0'being attracted to magnet 1 and the wire 9" being attracted to magnet 6.

In Fig. 1 the disks m and m are supposed to be transparent, being ofglass or -mica, so that the construction relatively to the wires 7' r 1"0" and the projections 0 0 p 1) may be clearly seen and easilyexplained.

Referring particularly to Fig. 1, the number 1 1 was formed by the wire1" being moved to magnet at into the path of projection 0 on disk m andby the wire 0" being moved to magnet 6 into the path of projection 19 ondisk on. The disks are stopped when the figures 1 and 4 are opposite thearrow. This number being indicated, the operation of indicating anothernumber-12, for example-would be as follows: The wire 0" being moved tomagnet 4 and the wire '2' to magnet 5, the disk m would be preventedfrom rotating by the action of wire 0" 011 projection 0'. Meanwhile thedisk m is rotated by the friction between it and tube j and disk atuntil it makes a halfrevolution, when it is stopped by the action ofwire r on projection 19. In like manner other numbers are formedopposite the arrow by the different combinations of the figures on onedisk with those on the other disk. By making the disks in m larger andputting the indicating-11umbers near their peripheries there will beplenty of room for multiplying the number of the magnets 1 2 3, &c., sothat a large number of rooms, say two or three hundred, may be equippedwith the invention successfully.

The electric circuits may be described as follows: Referringparticularly to Fig. o, it represents an electric battery. One pole u isconnected by electrical conductors to and through the magnets 3 at 7 8and to one terminal o of each pushbutt-on or circuit-closer located inthe respective rooms or sections of a hotel. The other pole a isconnected by conductors to and through magnets 1 2 5 6 and to oneterminal '0 of each circuit-closer above mentioned, the saidcircuit-closers being in multiple arc and the armatures q and wheel clbeing in multiple arc to each other. The pole to" is also connected byconductors through the magnet a to the wheel (1, and also p to thearmatures q and q". The brush or spring g is connected to the armaturesq and q electrically. One terminal of each magnet 1 2 3 at 5 6 7 8 has acontact-terminal, re spectively, 10 w 20 w w w 106 10 the first two wand w terminating in the path of the vibratory armature q, the secondtwo 10 10 terminating in the path of the vibratory armature q, the thirdtwo w and 10 terminating in the path of the vibratory armature q, andthe fourth two 10 and to terminating in the path of the vibratoryarmature q. The armatures q and q are electrically united by theconductor 03, and the armatures q and q' are electrically united by theconductor 33'. Vhen any circuitcloser-for instance, the one at the upperleft-hand corneris closed by pressing upon the terminal 4;, a current isestablished through magnet 1 and magnet The armature will be attractedto magnet 1, closing the terminal 14; through magnet a, which will bymeans of the mechanism describednamely, the ratchet-wheel (l andvibrating armature-rotate the hube as long as the finger is kept uponthe terminal 7). On account of the piece or insulation f being inpractice many times smaller than represented, the metallic portion ofthe hub e will come in contact with the brush g before the operator canhave time to remove the terminal 1: from the terminal r. Consequently acurrent will be established through the magnet a, the wheel (I, thearmature q, the magnet 3, and the battery until the hube has rotated sofar as to bring the insulation f again in contact with the brush g, andthereby interrupt the circuit through the magnet a. During the time ofthis revolution of the wheel (Z and disks m and m, the wires 0' and 1"come into the path, respectively, of the projection p, placing number 1on the disk m opposite the arrow Y and into the path of the projection0, so that the disk on would stop with figure 3 opposite the arrow Y.Therefore the annunciator would announce the upper lefthandcircuit-closer as being in room 31.

It is unnecessary to explain the operation in reference to the othercircuit-closers, as the explanation would be exactly similar. Afterremoving the terminal 1; from the terminali/ at the upper left-handcorner, the battery it remains closed through the magnets 1 and 3,because the armatures q and q are electrically connected, respectively,to the terminals to and w. The circuit is again broken by thecircuit-breaker or insulation f. The upper disk m is transparent to showthe numerals on the disk m I claim as my invention 1.. In an electricannunciator system, the combination of rotating concentric disksrotating together but independently movable, circuit-closers atdifierent points, as in the rooms of a hotel, an electro-magnet incircuit with each push-button and provided with an armature, and twoprojections upon each of said disks at different distances from thecenter, the said armatures being so located that any attracted armaturelies in the path of one of said projections, and an electric generatorin circuit with said magnets and said push-buttons, indicating-numeralsbeing upon said disks.
